CUTTER-HEAD.

SPECIFICATION forming part of Letters Patent N O. 684,151, dated October 8, 1901.`

Application filed April 16, 1901. Serial No. 56,097. (No model.)

To coll wir/0777, t may concern:

Be it known that I, CHARLES HENRY WEST, a citizen of the United States, and a resident of Estabutchie, in the county of Jones and State of Mississippi, have invented a new and Improved Cutter-Head, of which the following is a full, clear, and exact description.

This invention relates to a cutter-head designed especially for cutting flooring to form the tongue on the edge thereof.

The object of the invention is to provide an arrangement by which the cutters or bits will be held securely and in position properly to form the tongue without involving the danger of splitting and tearing the wood.

This specification is a specic description of one form of the invention, while the claims are definitions of the actual scope thereof.

Reference isto be had to the accompanying drawings, orminga part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a vertical section of the invention. Fig.2 is abottom plan view thereof. Fig. 3 is a fragmentary perspective view showing the head and the key, and Fig. 4 is a View showing the same parts and their relation to the bit-carrier.

a indicates the shaft on which the head b is mounted. The bits are held by a carrier, which is preferably made up of two disks c, secured rigidly together and fastened to the head h by screws CZ passing through the disks or plates c and into the head.

e indicates the cutters or bits, which are formed with shanks e', these shanks being seated in cavities c', formed in the carrier. The bits e are held in place by keys f, tted in cavities c2, formed in the carrierV and constituting, respectively, continuations of the cavities c. The edge walls of the cavities c and c2 are double beveled, as shown in Figs. l and 4, and the engaging edges of the Shanks e' and keys fare grooved so as to fit securely in connection with the edges of the cavities. Each shank e' has a depression e2 therein,and in these depressions, respectively, tit the tongues or projections f of the keys f. The keys f serve to hold the cutters in place, and the keys are themselves held in position by bolts g, which are engaged in recesses f2,

formed in the keys (see Figs. 3 and 4) and which pass through the carrier. The bolts thus arranged hold the keys rigidly in place, and the cutters or bits are prevented from displacement by these means.

As mentioned above, I prefer to form the carrier out of two disk-like plates fastened together, and when this construction is employed the cavities c and c2 are formed alternately, one in each plate. Referring to Fig. 4, it will be seen that one of the plates c, in which' the cavaties c and c2 are there shown as formed, lies directly against the other plate, and this other plate forms a side wall for the cavities. The Shanks e of the bits and the keysf'lie in these cavities and against the other plate c, and by this arrangement the parts e andf are held firmly in position. The plates c are formed with tangentially peripheral sections intermediate the bitse, such tangentially peripheral sections culminating in shoulders, (indicated at h in the drawings,) these shoulders lying directly against the cutters, at the backs thereof, and serving to brace and securely hold the same. Each cutter e comprises an edge e3 and a grooved portion e4, asbest shown in Fig. 3. According to the arrangement here shown the cutters are arranged in two peripheral lines, with the grooves e4 inward, Fig. l shows the position of the cutters with reference to the work, which is indicated at the point t' in Fig. 1. The cutters work on opposite sides of the tongue, the edges e3 forming the perpendicular surfaces of the edges of the plank and the grooved portion e4 forming the tongue. By means of this construction I am enabled to place upon the cutter-head a far greater number of bits than have ever been employed, and this increased number of bits enables me to cut the planks evenly and smoothly. The

IOO

sets of bits, the members of each set of which are arranged in peripheral alinement and the two sets working together on each side of the tongue of the plank to jointly form said tongue. With the construction which I have described all of the parts are capable of easy access, and the various elements of the cutter-head may be taken apart for repair or ad justment wi th very little trouble. Y

Having thus described my invention, VI claim as new and desire to secure by Letters Patentl l. A cutter-head of general .circular contour formed with seats in its side face adjacent to and communicating with its periphery, the peripheral edges of the cutter-head intermediate the seats being disposed tangentially or spirally and culminating in shoulders terminating at the seats, and bits secured in the seats against the shoulders.

2. A cutter-head having seats formed in its side faces and communicating with its periphery, bits having Shanks projected into said seats, keys tted in the seats and having Y z5 1' fastening devices lying inwardvof the periph- Y f interlocking engagement with the shanks,and
